This application claims the benefit of U.S. Provisional Application No. 60/857,098, filed Nov. 6, 2006, which is incorporated herein by reference in its entirety.
This invention relates to an improved top cap arrangement for use on upright wall panels associated with a wall system.
Interior wall systems formed from a plurality of upright interior panels which are typically serially joined in aligned and/or transverse relationship are conventionally utilized in offices and the like to divide large open areas into smaller work spaces. The upright wall panels are typically manufactured in the factory with final assembly occurring at the job site, which final assembly typically involves attachment of removable cover pads to opposite sides of the upright panel frame, and attachment of various trim pieces along the edges, such as a top cap along the top edge of the panel. In many instances the top cap is solely for trim purposes and imparts little, if any, structural integrity to the wall panel. In recent years, however, some panel assemblies have been developed which employ a structural top cap, although many of these known arrangements have involved either undesired size or structural complexity, or have provided limited functionality.
Interior space-dividing wall systems of the type described above generally permit panels to be joined in right-angled relationship to one another, such as L-shaped or T-shaped configurations, although the perpendicularly joined panels are typically joined at the panel edges. In recent years other connection techniques have been developed whereby one upright panel can be perpendicularly joined to a second upright panel, with the joinder being disposed at a location which is displaced from the upright edges of the second panel, specifically at a location disposed between the upright edges. This is commonly referred to as an “off-modular” mounting, that is the mounting is not limited to locations corresponding to the end edges of the individual wall panels. Many of the off-modular connection techniques utilized for joining two perpendicularly-related panels, however, have involved either complex arrangements or, more significantly, have presented limitations with respect to the forces or loads transferred between the connecting structure and/or have resulted in a rather complex assembly process.
Accordingly, it is an object of this invention to provide an improved top cap arrangement for an upright wall panel, which improved top cap arrangement is believed to provide improved characteristics with respect to both the structure of the upright panel and the ability thereof to structurally permit off-modular joining between perpendicular panels, thereby improving upon the overall characteristics in a manner which is believed to overcome some of the disadvantages associated with prior systems.
More specifically, this invention relates to an improved upright space-dividing wall panel having an internal frame which permits pads or covers to attach to opposite sides thereof, and a horizontally elongate top cap which rigidly attaches to a top rail of the frame and extends throughout the lengthwise extent of the wall panel. The top cap is preferably constructed as a monolithic one-piece metal structure which secures to the frame top rail by a plurality of threaded fasteners disposed in spaced relationship along the lengthwise extent of the top cap. The fasteners engage internally of the top cap so as to be not externally visible.
The top cap in a preferred construction is lengthwise extruded of aluminum, and defines a downwardly-opening bottom channel extending lengthwise generally along the centerline thereof, which channel has a generally T-shaped cross-section whereby enlarged heads of threaded fasteners are slidably inserted within the channel from one end of the top cap and are non-visibly captivated in the channel so as to permit fixed securement of the top cap to the frame top rail.
The invention also includes a wall panel having an improved structural top cap, as aforesaid, wherein the top cap has secondary channels which open downwardly thereof and extend lengthwise of the top cap in parallel relationship to and generally on opposite sides of the center channel. The side channels cooperates with a top coupling brackets which can be slidably inserted into and positioned along the secondary channel at any location therealong to permit off-modular connection to a second panel which is disposed adjacent and extends perpendicular to the adjacent side of the panel on which the coupling bracket is mounted.
The wall system of this invention, as aforesaid, includes not only a top coupling bracket which structurally mounts directly on the top cap of a main panel and is slidable therealong for disposition at any desired location, but also includes a bottom coupling bracket which mounts on a lower pan or frame member of the main panel at any location therealong. The top and bottom brackets cooperate with upper and lower corners of a secondary panel so as to rigidly couple the secondary panel to the main panel in a perpendicular off-modular relationship, with significant loads generated by the secondary panel being transmitted through the top bracket to the structural top cap of the main panel.
Other objects and purposes of the invention will be apparent to persons familiar with constructions of this general type upon reading the following specification and inspecting the accompanying drawings.
Certain terminology will be used in the following description for convenience and reference only, and will not be limiting. For example, the words “upwardly”, “downwardly”, “rightwardly” and “leftwardly” will refer to directions in the drawings to which reference is made. The words “upper” and “lower” will also refer to portions of the panel when in its normal vertically-oriented position of use. The words “inward” and “outward” will refer to directions toward and away from, respectively, the geometric center of the panel and designated parts and assemblies associated therewith. Said terminology will include the words specifically mentioned, derivatives thereof, and words of similar import.
The wall panel 10, as illustrated by
The interior frame 11 may assume other known constructions but, in the illustrated embodiment, is of a generally open but rectangular rigid construction defined by horizontally elongated and vertically spaced top and bottom frame rails 14 and 15, respectively, which frame rails in turn are rigidly joined adjacent opposite ends thereof by upright edge or side rails 16 which extend vertically in generally perpendicular relationship to the horizontal rails 14-15. The frame rails 14, 15 and 16, in the illustrated and preferred construction, are rigidly joined, such as by welding, and each is preferably formed from an elongate hollow metal tube having a cross-section which is generally rectangular and more specifically generally square. The frame rails, including specifically the uprights 16, are provided with openings through the side faces thereof which, in a conventional manner, accommodate clips or hooks provided on the cover pads 12 for permitting the cover pads to be attached to the frame substantially in engagement with the side faces thereof. The frame 11 as illustrated by
In the frame 11 as illustrated by
The pan 21 has upwardly protruding side flanges 23 which extend upwardly adjacent opposite sides of the bottom wall and protrude lengthwise therealong, whereby the bottom pan 21 has a generally cup-shaped upwardly-opening configuration, and has a width which generally corresponds to the width of the frame uprights 16 and associated cover tiles 12. The bottom pan side flanges 23, at the upper lengthwise-extending extremities thereof, are provided with upper edge parts 24 which are initially bent inwardly and then upwardly so as to define a shoulder or step on which a lower horizontally extending edge of a removable side cover or tile 12 can be positioned.
The lower end part 18 of each frame upright 16 also has, as illustrated in
The structural top cap 13 includes a main generally horizontally oriented top wall 31 which has a pair of generally parallel and sidewardly spaced side walls 32 joined thereto and cantilevered downwardly therefrom. These side walls 32, which extend throughout the entire length of the top cap 13, are sidewardly spaced by a distance which generally corresponds to the width of the top frame rail 14. This latter frame rail 14, as well as the other frame rail members, preferably has the side walls thereof provided with slight depressions 44 formed therein adjacent the opposite lengthwise extending edges of the respective side wall, and these shallow depressions 44 as defined on opposite sides of the top frame rail 14 accommodate therein the downwardly cantilevered side walls 32 substantially as illustrated in
The top cap 13 also includes an elongate downwardly-opening channel 34 which is defined under the top wall 31 and extends lengthwise generally along the centerline thereof. This channel 34 is defined by a pair of sidewardly spaced side flanges 35 which extend lengthwise of the top cap in generally parallel relationship, and which are cantilevered downwardly from the top wall 31 on opposite sides of the longitudinally or lengthwise extending centerline. The side flanges 35 are spaced inwardly from the side walls 32, and are provided at their lower edges with inwardly turned retaining flanges 36 which are disposed in opposed aligned relationship to one another. These lower retaining flanges 36 define a narrow slot 37 therebetween which extends lengthwise of the cap and defines the mouth or access opening into the channel 34, which channel has a greater width than the mouth 37. This channel 34 and its access opening or mouth 37 hence is generally T-shaped in cross-section.
As further illustrated in
As illustrated by
To fixedly secure the structural top cap 13 to the upper edge of the panel frame 11, a pair of fasteners 45 are provided for cooperation between the cap 13 and the top frame rail 14. The fastener 45 is preferably a conventional carriage bolt having an elongate shaft 46 provided with an enlarged head 47 at the upper end. The shaft 46 has a square portion 46A directly below the head 47 so as to permit the bolt 45 to be slidably moved lengthwise along the channel 34, while at the same time restricting rotation of the bolt. The lower end of the shaft 46 is threaded and adapted to have a conventional nut 49 threadedly engaged thereon. The shaft 46 of the carriage bolt is adapted to extend through aligned openings 48 formed in the top and bottom walls of the top rail 14 so that the nut 49 can be threaded onto the lower protruding end of the shaft 46 to securely draw the top cap 13 down into seated engagement with the top rail 14 as illustrated in
The top cap 13 is preferably secured to the top rail 14 by two or more carriage bolts carried thereon in spaced relationship therealong, whereby the carriage bolts align with openings 48 which extend vertically through the top rail so as to permit the top cap to be moved downwardly and seated on the top rail while enabling the bolts to project therethrough, following which the nuts are secured so as to draw the cap into snug engagement with the top rail.
As an alternative mounting technique, the bolts 45 can be initially inserted through the openings 48 in the top rail 14, and then the top cap 13 is disposed in laterally offset but aligned relationship with the top of the panel frame so that the bolt head 47 of the first bolt is located directly adjacent the free end of the top cap. The bolt can be manually raised a small extent so as to enable the top cap 13 to be slidably displaced so that the head 47 of the bolt enters the channel 34. The top cap 13 is progressively slidably displaced lengthwise along the top rail 14 until all of the bolt heads have been slidably inserted into the channel 34, and the top cap is properly aligned so that the ends of the top cap correspond to the edges of the frame. The nuts 49 can then be engaged and tightened to draw the top cap 13 against the top rail 14.
In either case, the bolt head 47 is not restricted longitudinally to any specific location along the length of the top cap 13 and the channel 34 thereof. While the bolts 45 do correspond to the respective bolt openings 48, the specific position of the top cap 13 may be set longitudinally before the nuts 49 are tightened to fix the top cap 13 in position. As a result thereof, the position of the top cap 13 relative to the ends of the wall panel 11 may be precisely aligned before the nuts 49 are tightened.
The aforementioned top cap and top rail arrangement, and particularly the structural characteristics provided by the top cap 13 and its manner of seating on the top rail 14, provide significant strength and rigidity to the overall frame, and to the assembled upright panel. After the top cap 13 has been secured using either of the techniques described above, then the side covers 12 can be attached to opposite sides of the frame, which side covers have outer surfaces disposed so as to be substantially flush with exterior sides defined by the edge flanges 41 of the top cap.
While the retaining flanges 36 which define the narrow slot 37 can be notched at selected locations so as to permit the bolt head 47 to be inserted upwardly and then slidably displaced sidewardly into the channel 34, such notching complicate the overall construction of the top cap and increases the overall cost. Accordingly, by forming the top cap as an elongate extruded metal element, without thereafter carrying out further notching or machining operations for permitting vertical insertion of the bolt heads, a highly desirable structural top cap can be provided at a more economical cost.
Referring now to
To effect fixed perpendicular securement of the secondary panel 10A to the side face of the primary panel 10, an upper connecting bracket arrangement 52 cooperates between the top cap 13 of the primary panel 10 and the upper corner of the secondary panel 10A. In addition, a lower or bottom connecting bracket arrangement 53 couples between the bottom frame element of the primary panel 10, and the bottom frame element of the secondary panel 10A.
The top bracket arrangement 52, as illustrated by
As shown by
The main support plate 56 of the bracket member 54 has a pair of openings 61 extending therethrough, which openings are disposed generally on a centerline which extends transverse to the edge rail 57. The openings 61 accommodate therein threaded fasteners or screws 62 which are provided for connecting the first bracket member 54 to the second bracket member 55.
As to the second bracket member 55, it has a generally L-shaped configuration, preferably being bent from flat metal plate, and includes a top leg or plate 63 and a side leg or plate 65 which is joined to one edge of the top leg 63 and protrudes vertically downwardly therefrom in substantially perpendicular relationship thereto. The top leg 63 has a pair of threaded openings 64 extending vertically therethrough generally along the transverse centerline. The openings 64 are positioned to align with the openings 61 when the plate 56 is positioned over the plate 63 so that the threaded fasteners 62 can be engaged therewith to rigidly couple the plates 56 and 63 together as illustrated in
The vertical or down leg 65, at the lower edge 67 thereof, has a downwardly cantilevered mounting flange 66 which is generally Z-shaped in longitudinal cross-section and functions as a hook. The vertical leg or plate 65 also has a threaded opening 68 extending therethrough at a location spaced upwardly from the hook 66. This opening 68 cooperates with a threaded fastener or screw 69 which is inserted through an appropriate opening formed in the outer side wall of the frame upright 16 (
The top leg or plate 63 also has, on the edge thereof opposite the side leg 65, a protruding edge part or extension 74 which, when the second bracket member 55 is secured to the frame upright 16 as illustrated in
To utilize the top bracket arrangement 51 to effect securement of the secondary panel 10A in an off-module perpendicular positional arrangement adjacent one side of the primary panel 10, the first bracket member 54 is initially fixed to the panel 10, and the second bracket member 55 is initially fixed to the secondary panel 10A, prior to these panels being joined. This is accomplished by initially inserting the T-shaped guide rail 57 into the end of the selected guide channel 38 associated with the top cap 13 of the panel 10, as illustrated by
The second bracket member 55 is also initially fixedly mounted to one of the upright edge rails 16 associated with the secondary panel 10A. To effect this mounting, the second bracket member 55 is oriented so that the vertical plate 65 protrudes downwardly, whereupon this plate 65 is manually moved downwardly into the interior of the edge rail 16. When substantially fully inserted, the lower hook 66 aligns with a slot or opening 72 (
With the first and second bracket members secured respectively to the cap 13 of panel 10 and edge rail 16 of panel 10A, the panel 10A is then moved so as to be positioned perpendicularly adjacent the side of the panel 10, whereupon the main plate 56 of the bracket member 54 is positioned directly over the horizontal plate 63 of the bracket member 55. The screws 62 are then inserted through the aligned openings 61 and 64 so that the horizontal plates 56 and 63 are fixedly drawn snugly together to create a strong and rigid connection between the structural top cap 13 of primary panel 10, and the adjacent upright edge rail 16 of the secondary panel 10A. It should be noted that the securing screws 62 are positioned so that the heads thereof protrude upwardly into the mouth or slot 37 associated with the channel 34 so as to not only be hidden by the top cap 13 associated with the panel 10A, but also not interfere with mounting of the top cap. This bracket arrangement hence enables the top caps 13 and 13A of the connected panels to be maintained in a flush or level relationship, while at the same time maintaining the end of the top cap 13A closely adjacent the side edge of the top cap 13, all as illustrated by
Considering now the lower connecting bracket arrangement 53, and referring specifically to
The lower main bracket member 77 has pairs of sidewardly-spaced openings 78 formed therethrough adjacent one edge thereof, and has a further pair of sidewardly spaced openings 79 formed therethrough adjacent the opposite edge thereof. These openings 78 and 79 are provided for permitting rigid securement of the bracket member 77 to the bottom pan 21 of the panel 10, and to the bottom pan 21 of the panel 10A, respectively.
When the panel 10A is being connected to the panel 10 in an off-module relationship substantially as illustrated by
After the lower bracket arrangement 53 has been fixed to the bottom pan of the main panel 10 and cantilevered sidewardly therefrom as illustrated in
It will be appreciated that the upper and lower brackets will be vertically aligned directly one above the other, and that the lower connecting bracket structure will be fixedly joined between the adjacent panels 10 and 10A first, with the upper bracket structure being fixedly joined thereafter. Due to the fixation of the upper bracket member 56 to the top cap 13 of primary panel 10 by means of set screws, it will be appreciated that these set screws can initially remain loose so as to permit slidable adjustment of the upper bracket member 56 during the assembly process, with these set screws being tightened at the end of the assembly operation so as to permit any small or fine sideward slidable adjustment of the upper bracket so as to ensure proper vertical alignment thereof with the lower bracket.
In addition to permitting perpendicular connection between primary and secondary panels in an off-module manner as described above, the top and bottom bracket assemblies and their cooperation between the primary and secondary panels also permits the secondary panel to be mounted in perpendicular relationship when the secondary panel is aligned generally with one vertical edge of the primary panel as illustrated by
As specifically illustrated by
While the connection arrangement of
Referring now to
The improved structural top cap 13 of the present invention is advantageous with respect to its ability to be formed of a length which is sufficient to span and be fixedly secured to the upper edges of two or more aligned panels. In this respect, reference is made to
It will be appreciated that the multi-panel length top cap 113 can extend across more than two panels, with the length of the top cap and its cooperation with a number of panels being determined principally by the practicality of being able to manufacture and transport the long top cap, such as by gaining access to a desired work site, and is also controlled by the size (i.e. width) of the individual panels which are serially joined in aligned relationship. Also, corner blocks may be inserted between the frames 10-1 and 10-2 with a third or fourth frame attached to the open faces of the corner blocks to define 3-way and 4-way corner configurations.
Preferably, it is also desirable to provide appropriate space-compensating members beneath the multi-panel length top cap 113 or the shorter top cap 13. More particularly, during the assembly process of the panel frame 11, the vertical frame rails 16 ensure that the elevational height of the ends of the top frame rail 14 is at a consistent and fixed vertical elevation. However, during the extrusion process of the frame rails 14, or during the assembly process thereof, it is possible that undesirable distortion of the linearity of the top frame rail 14 may occur and most typically, it may be found in the frame 11 that the top frame rail 14 may have a slight bow downwardly. As to the top caps 13 or 113, however, it is highly desirable to maintain a constant linear shape of the top cap 13 or 113 since any bowing or waviness of such top cap could prove to be readily noticeable. Hence, the top cap arrangement of the invention also accommodates and eliminates the possibility of such undesirable distortion or waviness along the top cap.
More particularly as illustrated in
It will be understood that while
With the improved structural top cap 13 or 113, and specifically its structural cooperation with the top and bottom bracket arrangements 52 and 53 including specifically the direct structural connection between the top cap and the upper bracket assembly 52, a highly improved structural arrangement having improved strength and rigidity, and hence dimensional control, is achieved while at the same time providing improved access and connectability with respect to joinder of a secondary panel in perpendicular relationship to a primary panel, particularly in an off-module relationship.
In addition to the improved features of the wall panels 10 as described above, each wall panel 10 also preferably is included with an end trim cover 120 as seen in
More particularly as seen in
Generally, the interconnection of the trim covers 120 or 120A with its associated top cap 13 or 113 is accomplished through an identical locator clip 130 which is insertable horizontally sidewardly into engagement with the open end of the top cap 13 or 113 as indicated by reference arrows 131. Once the locator clip 130 is fitted into position in the associated top cap 13 (113), as seen in
More particularly as to
Still further as best illustrated in
More particularly as to the locator clip 130, this locator clip 130 is preferably formed of a suitably rigid material such as plastic and has a main central body 145 having an upward opening U-shape as seen in
To locate the trim cover 120, the main clip body 145 includes a downwardly depending leg 147 which is located exteriorly of the top cap 13 and terminates at its lower distal end in a locator ledge 148. This locator ledge 148 thereby projects horizontally outwardly from the end face of the vertical frame rail 16 (16A) for engagement with the corresponding trim cover 120 or 120A.
Turning next to
To prevent removal of the trim cover 120 from the associated panel frame 11, the inside face 150 of the trim cover 120 is provided with a cantilevered spring clip 160 proximate the upper end thereof. This spring clip 160 includes a fixed upper end 161 and a distal free end 162 formed at the end of the resiliently cantilevered spring body 163. This free end 162 is spaced inwardly from the trim cover face 150 and is aligned for insertion into a corresponding T-shaped window 164 that is formed in the vertical frame rail 11. This window 164 has a generally rectangular T-shape defined by a wide upper section 165 and a narrow bottom section 166. Normally, this T-shaped window 164 accommodates a carriage bolt which is inserted horizontally therethrough to join two serially-adjacent panel frames 11 together. However, at the end of run position as depicted in
